PLN 24

The article "The Falkirk Wheel" by Alan Bellows introduces the idea of using a pulley system instead of using locks to get a boat from one water height to another. This wheel uses gravity to lower boats from the bridge to the river below. There are two arms on the wheel which are both filled with water and can hold four, 20 yard long boats at a time. The two wheels are very energy efficient using mostly gravity and as a result they only use 1.5 kilowatts per hour. This matters to me because this is a great idea and will inspire future creativity. This matters to the world and education because it should inspire other countries to try to integrate this idea into other countries.
